Positive ROAS in the first full campaign cycle. We did not expect it quite that quickly.

The technical quality is the obvious thing to highlight. The automated test suite is comprehensive, the deployment pipeline is solid, and the documentation is actually useful rather than written to satisfy a checklist. But the metric I keep coming back to is what has NOT happened since go-live. No 2am incident calls. No emergency patches. No post-launch retrospectives about what went wrong. For a system of this complexity, that outcome is exactly what we paid for.

Project summary

OTA dependency was hurting our margins. A direct booking experience that could genuinely compete required an investment we had been postponing for too long.

Legacy-to-cloud-native in a timeline our previous vendor said was impossible

We went with a smaller team than we had originally planned for. I had concerns about whether the capacity would be sufficient given our timeline. Those concerns were unfounded. The team was focused, communication was constant, and the quality at each milestone review was consistent throughout. Smaller does not mean slower when the people are the right ones and this engagement proved that.

Project summary

Years of incremental development had left us with a platform that was functional but limiting. A structured rebuild was the agreed path forward.

The advice held up six months later when circumstances changed. That is good consulting.

Honestly, I came into this engagement with some scepticism. We had a bad experience with a vendor twelve months earlier and I wanted to see evidence of competence, not just hear about it. The discovery documentation was the first signal. The sprint delivery consistency was the second. By go-live I had stopped being sceptical and started planning how to expand the engagement. The production system has been stable from day one and our internal team loves working with the codebase they left us.

Project summary

A new commercial property division required tooling that was fundamentally different from our residential platform. Extending the existing system was not viable.

Cross-platform build that genuinely felt native — testers could not tell the difference

I have been through several technology implementations in my career. The pattern I am used to is: detailed proposal, optimistic timeline, scope creep, overrun, excuses at the end. This engagement broke that pattern at every stage. The timeline was realistic from the start. Changes were managed through process. The final delivery matched what was agreed. Simple, but uncommon.

Project summary

The business case had been approved but the internal resource to execute it had not materialised. External delivery was the pragmatic solution.

Outsourced IT that simultaneously improved the service level and the cost line

The technical quality is the obvious thing to highlight. The automated test suite is comprehensive, the deployment pipeline is solid, and the documentation is actually useful rather than written to satisfy a checklist. But the metric I keep coming back to is what has NOT happened since go-live. No 2am incident calls. No emergency patches. No post-launch retrospectives about what went wrong. For a system of this complexity, that outcome is exactly what we paid for.

Project summary

A major enterprise client contract required API-level integration with their supply chain platform. We had thirty days to demonstrate capability and our existing system could not provide it.
